JOHN MAYHER, or EAST HAMPTON, MASSACHUSETTS.

Specification forming part of Letters Patent No. 1 10,928, dated January 10, 1871.

. To all whom it may concern:

Be it known that I, JOHN MAYHER, of East Hampton,in thecountyofHampshireand State of Massachusetts, have invented a new and Improved Attachment for Regulating the Discharge of Water from Pumps and 1 do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention consists in the combination of a pump and its induction and eduction pipes, with a connecting-pipe and valve, as will be fully described hereinafter, for the purpose of regulating the amount of water thrown from the pump.

Figure 1 represents a side elevation of my invention; Fig. 2, a plan view of the same.

To enable others skilled in the art to make and use my invention, I will now proceed to describe fully the construction and operation of the same.

A represents a pump of any suitable construction, which is provided with the usual supply and discharge pipes, aa.

b represents a pipe connecting the two pipes a a, which is provided with a valve, b, of any desired construction.

The supply-pipe may be connected in any proper manner to a boiler or other receptacle.

The operation is as follows: The supply of water delivered by the pump is regulated by the position of the valve in the pipe connecti-ng the supply and discharge pipes. If the valve is closed, the pump of course forces all pump for use in case of fire can use the same pump to supply the boiler, while heretofore two pumps were necessary, it being found in practice not to be economical to till the boiler, then stop thepump until the water evaporates, and then fill again. Then, again, it is impos sible to run a crank and fly wheel steam-pump at a sufficiently low rate of speed to give the required supply and have suflicient velocity to pass the center.

The connection described is extremely simple in its construction and efl'ective in action.

Having thus fully described my invention, what 1 claim as new, and desire to secure by Letters Patent, isv The combination of the pump A and supply and discharge pipes 11, a, with the pipe or passage b, having the valve b, as described.

This specification signed and witnessed this 30th day of November, 1870.

JOHN MAYHER.
